yes, i figured it out finally, and thank you for responding. I'm using gigabyte r9 290's, just got them today. but last night, when i posted my question, i was running r9 270's and getting 5 or 6 hw's per card, and then they would shut off after about an hour and i would have to re-up them again.
I hope I will not run into the same problem with the r9 290's. I'm not sure what the best settings are for them, if you could point me in the right direction, I would be grateful. I was getting about 440 hash per card at three cards last night, but the approximated hash at my pool, showed only 400-700 for all of them together, then finally jumped up to about 1100-1200 after fiddling with the settings, some.
Still having some issues syncing the wallet, i've downloaded 1.8.5, not quit clicking in yet, but I'm sure it will work. Best! -rc
